I NTRODUCTION In this project Bluetooth module is interfaced to 8051 microcontroller. This Bluetooth receives the commands from the Android application device using wireless communication. The program which is written to the 8051 microcontroller communicates with Bluetooth module serially to receive the commands. Microcontroller switches the electrical loads automatically based on the commands received from the Bluetooth

M OTIVATION Disabled people are more likely to be exposed to daily life problems than other healthy people. While deaf people cannot hear the door bell, Alzheimer diseased people can forget the gas open in the kitchen. These are some encountered examples when they 4 are alone at home. With the help of technology, assistant projects can be developed to overcome their difficulties. Smart homes can also be used to support disabled people, providing safe, secure and empowering environments. The system can allow the user to control many features or automate them. The environment can also be monitored by the smart home system to ensure safety and alert people when there is some dangerous situation.

OBJECTIVE To design an efficient Bluetooth control home appliance. So it can be easy to On or Off any electronic appliance like fan,lamp etc.

COMPONENT FUNCTIONS/SPECIFICATION Bluetooth module The Bluetooth module used in this project is HC-05 Linvor Bluetooth module. It is an easy- to-use Bluetooth serial port protocol (SPP) module, designed for a transparent wireless serial connection set-up. The module has 34 PINS for configuration/interfacing of Bluetooth module with microcontrollers. For setting up a Bluetooth module.

L IQUID C RYSTAL D ISPLAY (LCD) Most Common Lcds Connected To The Microcontrollers Are 16x2 And20x2 Displays. This Means 16 Characters Per Line By 2 Lines And 20 Characters Per Line By 2 Lines, Respectively. Our Project It Will Be Display Status Of The Lamp Or Motor, On Or Off

PLANNING OF THE WORK First we aware with all the components We can implement the power supply. We can implement the microcontroller. We can interface lcd with microcontroller Then we interface Bluetooth with microcontroller We work on programing.

SUMMARY In this project we can make the Bluetooth control home appliance.
